One of the gametypes introduced in the newest Unreal Tournament.

At the beginning of the round players get to choose which spawnpoint they want to spawn in that round (the player order for spawnpoint choosing is random, and is done in a way that every player gets to choose the first spawnpoint at least once per round). After the players get to choose the spawning points, the match begins.
Each round is basically regular Elimination/CA, but with items. The catch is that picked up items won't respawn until the next round.
It could be implemented in current Elimination as two cvars, one for spawnpoint choosing (regardless if team_CTF_*spawnpoints are present) and another for item spawning (in this case, instead of spawning with every weapon with max ammo, players would start with just Gauntlet and Machinegun).
